*Product Life Cycle - Opportunities for Digital and Sustainable Transformation*

challenging aspects in quantifying to a CE, limiting its practical transition, the remaining parts of the chapter are structured in the other three sections. Section 2 presents the methodological approach adopted by the authors to boost an effective shift to a CE through the adoption of the innovative tool ViVACE® able to provide useful quantitative information. In particular, this Section describes the main implemented/ongoing applications of the tool in different industrial sectors, according to several purposes. Section 3 analyses and categorizes the previously described applications to demonstrate the potential of the tool in terms of coverage of, e.g., different sectors, actions within the CE umbrella concept, and scales. This standardization supports an easy replication of the tool in other contexts and upscaling according to different implications. Finally, Section 4 describes the main conclusions, recapping the contribution that the wide use of the proposed tool could provide for the identification and measurement of unexplored circular initiatives through a quantitative demonstration of their effectiveness.
